Abstract (en)

[origin: WO2015197227A1] A calibration device (1) for calibrating a scattered light meter designed to measure a particle concentration, especially in motor vehicle emissions, comprises at least one scattering member (2) which, upon being irradiated with light (11), emits scattered light (20) at an intensity and distribution defined by the scattering member (2). The calibration device (1) further comprises a calibration light source (7, 7') which is disposed inside the scattering member or on an outer surface of the scattering member.
